How can road construction in mountainous areas exacerbate mass wasting?
 
  What will be an ideal response?

Question 2

You are driving along a mountain highway built into the side of the mountain. The rock layers making up the slope are oriented parallel to the slope. What are three ways that the slope could be stabilized to reduce the likelihood of landslides?
 
  Indicate whether this statement is true or false.

Answer to Question 1

Answer: Many mountainous areas have steeply inclined rock layers. During road construction, these layers are incised to create a flat surface for the road. This leaves steeply inclined layers with nothing but friction to hold them in place. If the force of friction is overcome (i.e., precipitation migrates along the bedding plane), the rock layers will collapse.

Answer to Question 2

Answer: Answers will vary but can include bolting down the slope face, stepping back the angle of slope for some weaker layers, and removing material entirely.
